6. Proper phone maintenance.
Proper use of the battery
Battery in this device can be charged with a charger. If the battery level is low,
recharge it. To prolong battery life, let it discharge before connecting the
charger. If not used, unplug the charger from the phone. Excessive charging
causes shortened battery life.
The temperature of the battery has an impact on its charging cycle. Prior to the
charging process, cool the battery or raise its temperature so that it is similar to
the room temperature (approx. 20ºC / 68ºF).
If the battery temperature exceeds 40ºC / 104ºF) the battery must not be
charged! Use the battery only according to its intended purpose. Avoid leaving
the battery within a magnetic field range, because it shortens its life. Do not use
a damaged battery The battery lifespan can be shortened if it has been exposed
to very low or very high temperatures - this causes interference to the phone,
even when the battery has been properly charged. Do not throw the battery
into flames! Do not throw a worn-out battery –send it or return it to an
authorized recycling point.

accessories out of reach of children. Avoid exposing the phone to the high and
low temperatures; it can shorten the life of phone electronic components, melt
the plastic parts and destroy the battery. Do not try to disassemble the phone.

warranty. Exposing the phone to extreme temperatures can reduce the level of
protection. It is recommended that the phone is not used at temperatures below
0°C/32°F or higher than 40°C/104°F.
